" CATIGUE in Automobiles," by R. I.

Love, of the Motor Industry Research Association, is one of 70 papers to be presented at the International Conference on Fatigue of Metals to be held next autumn.

The Institution of Mechanical Engineers has arranged 10 sessions to be held in London from. September 10-14, and the papers will he presented again in New York from November ,28-30 under the guidance of the American Society of Mechanical Engineer's. The discUs siois in both places will be recorded, and, together with the papers, will be published by the Institution.

Other papers of interest to the road transport industry are: "Fatigue Effects in Automobile Engineering," by R. C. Mattson (General Motors); "Fatigue in Plain Bearings," by W. E. Duckworth and G. H. Walter (Glacier Metal Co.); "Influence of Residual Stresses in the Fatigue Limit,' by H. Sigwart (Daimler Benz); and "Effects of Shot Peening on the Fatigue Strength of Hardened and Tempered Spring ,Steel," by A. G. H. Coombs, F. Sherratt and I. A. Pope (University of Nottingham).

The papers will be divided into eight groups, for each of which a reporter will give a summary at the 10th session. This, and the opening session, will be held at the Central Hall, Westminster, and the other eight will be in the Institution's meeting hail. Other professional bodies have been invited to participate.

Eight visits have been planned (for September 17-21) to centres at which research on fatigue is being conducted.

NEW SEAMLESS FLEXIBLE TUBING

SEAMLESS metallic flexible tubing I.-) suitable for use in positions which are subject to vibration, has been developed by Compoficx Co., Ltd., 26 Grosvenor Gardens, London, S.W.6. Where the temperature does not exceed 250° C. and pressures are within 450 p.s.i. the tubing is made from a copper alloy.

For temperatures up to 400° C. and pressures up to 1,000 p.s.i. Monet metal or stainless steel is employed. Special assemblies are available for higher temperatures and pressures.

Bore sizes range from in. to 2 in., the standard types of fitting being a sleeve at each end into which rigid piping can be brazed, or with a sleeve at one end and a suitable R.S.P. union nut and nipple at the other.

The tubing, as made for the higherpressure range, should be suitable for use between a fuel-injection pump and injectors.
